Haven't been to Mount Rainier National Park in a while to fish, so I thought I try one of the small sub-alpine lakes at around 4,500 feet. The main attraction of this lake is the awesome view of Mount Rainier:

As for the fishing, it turned out that there were Brookies in this lake. I landed 11 Brookies in the 12 to 14 inch range. My friend landed 10 in the same size range, and he took this photo of a typical Brookie from this lake:

This lake also has a nice view of Unicorn Peak (6,871 feet):

Lots of hikers passing through, but no other anglers were seen. The water temperature was surprisingly warm at 70 to 71 degrees F. Normally I recommend ceasing to fish for trout at 70 degrees, but these Brookies were down deep around 28 to 32 feet down in cooler water, and the fishing regulations for the park are very clear about their policy of trying to eradicate non-native fish (like the Brookies). There is also no limit (either size or number) on the fish you catch in a park lake. In a park lake, you can fish for spawning fish and you are allowed to snag fish. This a quote from the park fishing regulations: “Retention or humane euthanization of non-native fish is encouraged to reduce competition and likelihood of hybridization with native fish, as well as to restore ecosystems for other native aquatic species. Euthanize fish as humanely as possible (i.e. a blow to the head followed by pithing or decapitation).” While I can technically understand why the park fisheries biologists want us anglers to either keep or kill the non-native fish, like the Brookies, Kokanee or westslope cutthroats, I just had a hard time killing those Brookies that we were catching. I released all the Brookies I landed. This does mean that continuing to fish when the water reaches 70°F or higher is ok, as any fish incidentally killed would help the park. However, I find it hard to believe that anglers alone can get rid of entire populations of non-native fish, as it only takes a few fish to rapidly re-populate a lake. It also seems to me that rotting fish carcasses would ruin the pristine environment that the swimmers at this lake enjoy. I am admittedly conflicted over this policy.

The wildflower meadows are pretty much done for the summer, but there are still a lot of wildflowers around, like Pearly Everlasting, Fireweed, Spiraea and these Rainier Gentians that are just opening up:

The mosquitoes and biting flies were surprisingly not attacking, and I didn't have to use any insect repellent.

About a half dozen hikers took a swim in the lake, mainly by the end of the trail, but one woman swam out to the middle of the lake where I was, close enough to be within casting distance, and it so happened that I hooked a fish at that moment, and she asked what kind of fish I had caught. I could tell from her accent that she was from Britain, and she confirmed that she was from London. She sounded just like the actress, Emma Thompson, and could have been Emma’s daughter, for all I know. That was a unique encounter that I doubt I’ll ever see again.

It was a nice summer outing and the view of Mount Rainier made it special.

Another great report Rex!

In high school, probably 1986 or so, some buddies and I hiked in and camped at (I think) this same lake. We just fished from shore but I remember my friend caught a Brookie for supper that evening.

What sort of tactics were you using? Sinking lines with trolled wet flies?

Thanks, Andy

Thanks! There is no camping at this lake, but a little further down the trail is another lake where camping is allowed, so I'd guess that you camped at that further lake.

Yes, full sinking lines were the way to go (Type 5 for me); whatever will get you down 30 feet as the fish were hugging the bottom in the deepest part of the lake. No fish were in the shallows or on the edges or drop-offs. My friend was slowly trolling wet flies down deep, whereas I was casting & stripping down deep. I don't think the particular fly pattern was that important, as getting the depth right was the critical factor. When the wind picked up, I anchored to get better depth control. For hike-in lakes, I just pack along a mesh bag and rope, and at the lake I put some rocks into the mesh bag to create an anchor. Saves having to pack in a heavy anchor.

You and Dave captured some great images, beautiful scenery! Does Dave starch and press his fishing shirts? ;-)

A great report Rex. High lakes with large sized brookies are rare in Mt Rainier, the Alpine Lakes and the North Cascades. Most of the time the brookies overproduce and stunt. I've discovered three high lakes which can produce 12" plus brookies. You've fished two of them!

WDFW recommends dropping the fish entrails into deep water at high lakes. You figure. The theory is that the fish entrails will provide nutrients for insects and it's better to dispose of entrails in the middle of the lake than to throw them along the shore where they will attract animals or bears close to campsites.

The North Cascades park proposed a similar trout-are-bad policy years ago but they backed off. There's a well known study which showed that when trout are present in high lakes other native species (e.g. native salamanders, frogs and insects) don't do as well. I think the North Cascades Park realized that some trout populations in North Cascades lakes are native and that some trout species don't reproduce so well so you can manage fish populations with careful stocking. Brookies are a mixed blessing. They are beautiful and it's nice to have lakes where you know you'll be able to catch fish but they are prone to overproduce. Most of the lakes on the WDFW overabundant fish list are brookie lakes.

Beautiful lake, fish and scenery Rex! Did you guys catch any rainbows? I really enjoy catching brookies as all of the local stocked lakes just have bows.....

Dave says that his shirts are just wash and dry shirts with no starch or pressing. But, those cuffs do look a lot nicer than mine.
 
My friend, Dave, is famous for taking that type of shot, but I don't even try for fear of dropping my phone or camera into the water while taking the shot. Also, when Dave leans forward in his float tube to take that shot, I worry that he is going to flip over forwards one of these days. I tell all my fishing buddies that I don't do mouth-to-mouth resuscitation, and that if they are going to drown themselves, to please do so at the end of the day so as to not interrupt the good fishing. :)

No, we didn't hook a single rainbow, only the Brookies. The Brookies at this lake were not as colorful as at some of the other sub-alpine lakes I've been fishing. I was hoping we'd find some westslope cutthroats, but none were seen. The park fishing regs say that they haven't planted any fish in the park lakes since 1972. I was told that the park gillnetted the lakes for awhile, which got rid of many of the westslope cutthroats, but not so much for the Brookies. With Brookie lakes, the fish populations boom and bust, so you're never really sure what you're going to find in them. One year you'll find tons of small ones, and then two years later, you'll find a smaller number of larger fish.

I was gunna say how many phones has Dave dropped in😅
 
Seems like the brookies aren’t stunted.....and are the only game in the lake, so why would they want to kill them and put in hatchery rainbows???
There is no plan to put in hatchery rainbows. The plan is to kill all the non-native fish, period.

None thus far, but I cringe every time I see him taking that shot. Dave isn't using a lanyard or waterproof case, so it is a risky move. But the photo is strikingly impressive.
 
Will there be anything left to catch without brookies from what you witnessed? I’m for survival of the strongest.....besides I like catching brookies!

It's hard to know for sure, as we didn't catch that many fish to make for a good sampling. But I would guess that the only fish species in this lake were Brookies, so if the Brookies were all killed off, and no fish are planted, there would be no fish to catch in there. That's the whole point of the park's policy; they want to return the lakes to their natural state before man arrived. Many of the lakes didn't have fish, so that's the aim of the park policy, as I see it in the park fishing regs (e.g., no limits, ok to fish for spawning fish, ok to snag fish). It makes sense from an environmental biologist's point of view, but for an angler, it means that most park lakes will be fishless if all non-native fish are eradicated. That's why I am conflicted on this, as I am an avid fly fisherman. I enjoy catching & releasing Brookies or westslope cutthroats, so it bothers me that we are trying to eradicate those species of fish that have naturalized over the past century. I also think it would be very difficult, if not impossible, to totally eradicate the Brookies at this point through angler effort and gill netting (but I'm not a fisheries biologist, so I don't know that for sure). We know that even the use of rotenone does not always totally eradicate the undesired fish (e.g., Beda Lake in central WA), and I doubt that the park biologists would allow the use of rotenone anyway. It's a conundrum, for sure. As I was catching those Brookies, it just didn't feel right to me to be killing them as the regs recommend. I'm not saying that this is the right stance to take on this issue, as I just don't know. Each individual will have to make up their own mind on this.
